Overview
Typically, LAN-based IP telephones use external power converters located at or near the desktop. The inline-power patch panel eliminates the need for external power sources; it is a standalone chassis that can be co-located with the Catalyst switch to provide -48 VDC power directly to the telephone through existing Catalyst family 10/100BaseTX switching modules. When used with an uninterruptible power supply (UPS), the inline-power patch panel can provide power to the telephone even in a power failure.
The inline-power patch panel has 48 RJ-45 input ports and 48 RJ-45 output ports (see Figure 1). There are two RJ-45 connectors per port for a total of 48 ports. Each input connector is internally connected to a corresponding output connector (input connector 1 is connected to output connector 1, and so on).
The RJ-45 ports serve as the physical network interfaces to the inline-power patch panel. The lower bank of ports provide 10/100-Mbps connection to the switch through RJ-45 connector pins 1, 2, 3, and 6. The top bank of ports provide -48 VDC power to the IP telephones through RJ-45 connector pins 4, 5, 7, and 8, in addition to transparently passing 10/100 Mbps data traffic on pins 1, 2, 3, and 6.

Safety Overview
Safety warnings appear throughout this note in procedures that, if performed incorrectly, might harm you. A warning symbol precedes each warning statement. This section describes the warning symbol used in this note.
Installing the Inline-Power Patch Panel
This section provides rack-mounting instructions for the inline-power patch panel.
Note
This unit requires 3.5 inches (8.9 cm) of rack-mounting space.
A rack-mount kit is included for mounting the inline-power patch panel in a standard 19-inch (48.3 cm) equipment rack with two unobstructed outer posts, with a minimum depth (between the front and rear mounting posts) of 19.25 inches (48.9 cm) and a maximum depth of 32 inches (81.3 cm). This kit is not suitable for racks with obstructions (such as a power strip) that could impair access to the inline-power patch panel.
Warning
Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system.
Required Tools
The following tools and equipment are required to install the chassis:
•
Number 1, number 2 Phillips, or 3/16-inch flat-blade screwdriver
•
Antistatic mat or antistatic foam
•
Your own electrostatic discharge (ESD) grounding strap or the disposable ESD strap included with the system
Note
For more information about ESD, refer to the Site Preparation and Safety Guide.
The following tools and equipment are required to install the chassis in a rack:
•
Rack-mount kit
•
Tape measure and level
Rack-Mounting Procedure
Use this procedure to install the inline-power patch panel in a rack.
CautionDuring this procedure, wear grounding wrist straps to avoid ESD damage to the unit.
Step 1
Prepare for installation as follows:
a.
Place the inline-power patch panel on the floor or on a sturdy table as close as possible to the rack. Leave enough clearance to allow you to move around the chassis.
b.
Use a tape measure to measure the depth of the rack. Measure from the outside of the front mounting posts to the outside of the rear mounting strip. The depth must be at least 19.25 inches (48.9 cm) but not greater than 32 inches (81.3 cm).
c.
Measure the space between the inner edges of the left front and right front mounting posts to ensure that it is 17.75 inches (45.09 cm) wide. (The chassis is 17.5 inches [44 cm] wide and must fit between the mounting posts.)
d.
Open the rack-mount kit and see the component checklist in Table 3 to verify that all parts are included.
Table 3 Rack-Mount Kit Checklist
Quantity Part Description2
L brackets
4
M4 Phillips pan-head screws
4
12-24 x 3/4-inch Phillips binder-head screws
Note
Figure 2 illustrates how to attach the front of the inline-power patch panel to the rack. You can also attach the rear of the inline-power patch panel to the rack, depending on the configuration of your rack.
Step 2
Note that the L brackets connect the chassis to the rack. You can mount the L brackets to the front or rear mounting holes of the chassis, depending on which end is in the front of the rack.
Note
Some equipment racks provide a power strip along the length of one of the rear posts. If the rack has this feature, consider the position of the strip when planning fastener points. Before installing the L brackets on the chassis, determine whether to install the chassis from the front or the rear of the rack.
Attach the left and right L brackets using the four M4 Phillips pan-head screws provided in the rack-mount kit (see Figure 2).
Figure 2 Attaching the L Brackets
Step 3
Install the chassis in the rack as follows:
a.
Position the chassis in the rack as follows (see Figure 3):
–
If the chassis front panel is in the front of the rack, insert the rear of the chassis between the mounting posts
–
If the rear of the chassis is in the front of the rack, insert the front of the chassis between the mounting posts
b.
Align the mounting holes in the L bracket with the mounting holes in the equipment rack.
c.
Secure the chassis using six (three per side) 12-24 x 3/4-inch screws through the elongated holes in the L bracket and into the threaded holes in the mounting post.
d.
Use a tape measure and level to ensure that the chassis is installed straight and level.

Cabling
This section provides cabling guidelines for connecting the inline-power patch panel to the
Catalyst switch and IP telephones.Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
Note
The inline-power patch panel should only be used to provide power to IP telephones, not 10/100 adapters. If the IP telephone has a power source, you can attach the telephone directly to the 10/100BaseTX port on the Catalyst switch. However, if the IP telephone has a local power source, the inline-power patch panel provides backup power when the local power fails or is removed.
Use these guidelines for your cabling connections (see Figure 4):
•
Use standard Category 3 or Category 5 UTP cable.
•
Connect a cable from the IP telephone to an RJ-45 port in the top bank of ports.
•
Connect a second cable to the corresponding RJ-45 port in the lower bank of ports, and then connect the other end of this cable to a 10/100BaseTX port on the Catalyst switch.

Verifying the Installation
•
Before connecting the cables, verify that all the port LEDs are amber and the status LED is green.
•
After connecting the cables from the inline-power patch panel to the Catalyst switch and IP telephone, verify that the port LED and status LED are both green.
•
Verify the link on the switch through the inline-power patch panel to the telephone.
•
Verify that the IP telephone powers up and the screen displays "Cisco Systems."
